Deformation anisotropy induced by presence of physical fields

An attempt is made to develop an internally consistent theory of plastic flow with anisotropic hardening induced by physical fields of arbitrary structure. Standard theories of plastic flow based on the assumption that the deformation anisotropy is induced by presence of plastic strain, strain rate and temperature. It is worth to be noted that the presence of plastic anisotropy may be induced by influence of another physical fields, like radiation, magnetic fields and so on.
